TECHNICAL FIELD

The present invention relates to tables.

BACKGROUND

Currently, flip-top tables include off-center legs, complex locking mechanism (e.g., which may be difficult to operate, especially by children), and pinching hazards. Some flip-top tables are heavy to avoid tipping, but are thus difficult to move.

SUMMARY

In various implementations, a table with an adjustable table top may be provided. The table top may be positionable in two or more different positions. The table may include a table top coupled to a frame. The frame may include legs and a crossbar. Locks may be utilized to inhibit movement of the table top from one position to another position. In some implementations, retractable stop(s) may be coupled to an end of a leg. The retractable stop(s) may inhibit pinching of a user's body parts, clothes, etc.

In various implementations, a flip-top table includes a table top, that is adjustable between a first position and a second position, and a frame. The frame may include two or more legs and a crossbar coupling at least two of the legs together. The frame may include first lock(s), second lock(s), and retractable stop(s). A first lock may include a first key coupled to a bottom surface of the table top, and a first slot disposed in the crossbar. The first slot may receive at least a portion of the first key. A first lock may inhibit rotation of the table top from the second position when the first key is engaged with the first slot. The second lock may include second key coupled to the crossbar, and a second slot disposed in the table top. The second slot may receive at least a portion of the second key. The second lock may inhibit rotation of the table top from the first position when the second key is engaged with the second slot. Retractable stop(s) may be disposed at least partially in an end of at least one of the legs. A retractable stop may include a housing and a spring. The housing of the retractable stop may include a slanted top portion. The spring of the retractable stop may be disposed at least partially in the housing. The retractable stop may include a first position, when a first force is not applied to the top surface of the retractable stop, and a second position, when the first force is applied to the top surface of the retractable stop. The first force may compress the spring. When the table top is moved from a first position to a second position, a bottom surface of the table top may contact at least one of the retractable stops prior to the table top being oriented in the second position. A force greater than the first force may be applied to the retractable stop to allow the table top to be oriented in the second position.

Implementations may include one or more of the following features. The first lock(s) may include bar key and slot locks, which include a bar key and a first slot. In some implementations, the flip-top table may include first coupler(s) and a second coupler. The first bar key(s) may be coupled to the bottom surface of the table top via a first coupler. A first coupler may allow a bar key to be at least partially rotated. The second hook key may be coupled to the bottom surface of the table top via the second coupler, and the second coupler may allow the hook key to be at least partially rotated. The flip-top table may include additional second coupler(s). The additional second coupler(s) may inhibit movement of the table top when the table top is oriented in the first position. In some implementations, at least one of the first couplers may inhibit rotation of the table top when the table top is in a third position. A top surface of the table top may be slanted in the third position of the flip-top table. The retractable stop(s) may return to the first position when the first force is removed from the retractable stop, in some implementations.

In various implementations, a flip-top table may include a table top and a frame coupled to the table top. The table top may be adjustable between a first position and a second position. The frame may include legs, a crossbar coupling the legs together, first lock(s), and second lock(s). The first locks may include a first key and a first slot, which may receive at least a portion of the first key. The first key may be coupled to a bottom surface of the table top. The first slot may be disposed in the crossbar. The first lock(s) may inhibit rotation of the table top from the second position when the first key is engaged with the first slot. A second lock includes a second key and a second slot, which may receive at least a portion of the second key. The second key may be coupled to the crossbar, and the second slot may be disposed in the table top. The second lock may inhibit rotation of the table top from the first position when the second key is engaged with the second slot.

Implementations may include one or more of the following features. In some implementations, the crossbar of the frame may coupling at least two of the legs together. The first key(s) may be disposed in the middle portion of the table top. In some implementations, at least one of the first keys may be disposed proximate a first end of the table top, and at least one of the first keys may be disposed proximate a second opposing end of the table top. The second lock may be disposed proximate the center of the crossbar. The second lock may be disposed on a surface adjacent to the surface of the cross bar on which the first slots are disposed, in some implementations. The crossbar may be disposed proximate a middle portion of the table top when the table top is disposed in the second position. In some implementations, each of the legs may include an arched foot and one or more wheels, which are coupled to at least one end of the arched foot. In some implementations, leg(s) of the frame may be extendable.

In various implementations, a flip-top table may include a table top adjustable between a first position and a second position. The flip-top table may include a frame coupled to the table top. The frame may include at least two legs, a crossbar coupling the two legs together, lock(s), and retractable stop(s). The frame may include locks, such as first locks and/or second locks. For example, a frame may include at least one second lock that includes a second key and a second slot. The second key may be coupled to the crossbar, and the second slot may be disposed in the table top. The second slot may receive at least a portion of the second key. The second lock may inhibit rotation of the table top from the first position when the second key is engaged with the second slot. The frame may include at least one retractable stop disposed at least partially in an end of at least one of the legs. A retractable stop may include a housing that includes a slanted top portion. The retractable stop may include a spring disposed at least partially in the housing. The retractable stop may include a first position when a first force is not applied to the top surface of the retractable stop, and a second position when the first force is applied to the top surface of the retractable stop. The first force may compress the spring of the retractable stop. When the table top is moved from a first position to a second position, a bottom surface of the table top may contact at least one of the retractable stops prior to the table top being oriented in the second position. A force greater than the first force may be applied to the retractable stop to allow the table top to be oriented in the second position.

Implementations may include one or more of the following features. In some implementations, applying the first force to at least one of the retractable stop may include applying a second force to the table top to compress the spring of the housing of the retractable spring. In some implementations, at least one of the retractable stops may be disposed in the second position when the table top is oriented in the second position. The retractable stop(s) may be disposed in the first position when the table top is oriented in the first position. A retractable stop may be disposed in each leg of the frame. In some implementations, at least one of the retractable stops may return to the first position when the first force is removed from the retractable stop. In some implementations, the flip-top table may include first locks that include a first key and a first slot. A first key may be coupled to a bottom surface of the table top, and a first slot may be disposed in the crossbar. The first slot may receive at least a portion of the first key. The first lock may inhibit rotation of the table top from the second position when the first key is engaged with the first slot.

DETAILED DESCRIPTION

In various implementations, a flip-top table may be provided. The flip-top table may include a table top, frame, and locks. In some implementations, the flip-top table may include retractable stop(s). The flip-top table may include a table top that is positionable in two or more positions. For example, the table top may be coupled to the frame to allow rotation of the table top between two or more positions, such as an upright position and a use position (e.g., horizontal to allow a media device to be positioned on the desk). Lock(s) may inhibit movement of the table top when the table top is oriented in a predetermined position (e.g., upright and/or use positions).

The table may be lightweight (e.g., an elementary student may be capable of moving the table). For example, the table may weigh less than 100 pounds. In some implementations, the table may be less than approximately 65 pounds. By providing lightweight tables, students, teachers, and other users may be able to move the table to different places with ease. For example, tables may be moved to different places in a classroom (e.g., to adapt to different learning styles and/or environments, for testing, to allow mixed uses of spaces), moved to storage, and/or moved to other spaces (e.g., other classrooms). In some implementations, to comply with testing requirements, a classroom may need more or less desks than ordinarily utilized. The flip-top tables may be quickly flipped to an upright position and moved to add or remove tables and comply with the testing requirements. In conference rooms, back up tables may be stored in an upright position and quickly deployed as needed (e.g., the stored tables may be moved into a location and the table top flipped to allow use). Lock(s) may facilitate moving the table(s) and/or using the table while inhibiting injury from the table top moving inadvertently, in some implementations.

The flip-top table may include a table top, a frame, and lock(s). The table top may include a planar portion. For example, a top surface of the table top may include a planar portion to allow writing, drawing, positioning of media device(s) (e.g., without falling off the top surface of the table top), etc. A bottom surface of the table top may include one or more locks or portions thereof.

The table top may include any appropriate material, such as plastic, wood, composite materials, etc. The table top may include a cross-section in a first plane and a depth perpendicular to the first plane. The cross-section and depth of the table top may have any appropriate dimensions. The shape of the cross-section may include any appropriate shape, such as rectangle, square, oval, triangle, trapezoidal, and/or any other appropriate regular or irregular shape. In some implementations, a plurality of tables may include complementary shapes to allow positioning of a set of tables together in predetermined shape(s). For example, tables may have a cross-section similar to a triangle and/or trapezoid, and a set of tables may be positioned together to form a row, rectangle, hexagon, octagon, etc. In some implementations, the tables may have a cross-section similar to a rectangle and a set of the tables may be positioned together to form a row, rectangle, square, etc.

The tables may have table tops that can be oriented in more than one position. The table top may be flipped (e.g., rotated about an axis) to move the table top between positions. For example, the table top may be coupled to the frame to allow rotation between positions. In some implementations, the table top may be coupled to the frame via a hinge or other coupling mechanism that allows at least partial rotation of the table top about the hinge.

The table top may be oriented in a first position in which the table top is upright (e.g., approximately parallel to the length of the legs and/or an end of the table top contacting the frame). The table top may be oriented in the first position to move the table and/or for storage. For example, the table may be more compactly stored when the table top is oriented approximately parallel to the legs of the frame (e.g., since several tables may occupy the same footprint as a single table that is in a use position). In some implementations, the table may be moved in the first position to reduce bumping with other objects and/or people. For example, in a classroom, when moving tables, to inhibit bumping with other tables, kids, and/or bookcases, the table top may be oriented in the first position.

The table top may be oriented in one or more use positions. For example, the table top may be oriented in a second position or one or more third positions. In the second position, the table top may be disposed approximately perpendicular to the legs of the frame. In the second position, the table may be used for writing, reading, classroom instruction, viewing media on media devices (e.g., tablets, computers, etc.), and/or other appropriate purposes.

In some implementations, the table top may be oriented in one or more third positions in which the table top is slanted relative to the legs (e.g., between 0 degrees and 90 degrees and/or between 90 degrees and 180 degrees). For example, the table top may be oriented in a third position to serve as an easel, reading table, media viewing table, etc. In some implementations, the table top may be oriented in a third position to facilitate use in drawing (e.g., drafting tables). The table top may be oriented in a third position that provides a slight slant to the top surface of the table top. The slight slant may provide a more ergonomic table top surface for writing while not causing objects (e.g., books, paper, media devices, etc.) disposed on the surface to slide off the table.

The frame of the table may include legs and a crossbar. The frame, legs, and/or crossbar may have any appropriate dimensions. For example, the frame may have dimensions based on the use of the table (e.g., student desk, drafting table, projector table, exhibit hall table, etc.). The frame may have a strength to support the table top in its predetermined positions. The frame may have a strength to support the table top and/or other weights (e.g., objects such as books and/or media devices resting on the table top; people for example sitting on top of the table top).

The legs of the flip-top table may have similar or different shapes and/or dimensions. A leg of the flip-top table may be C-shaped, U-shaped, L-shaped, and/or any other appropriate shape. In some implementations, at least a portion of the legs may include conduit. The conduit of a leg may have a cross-sectional shape similar to a rectangular, a rounded corner rectangular, an oval, a circle, and/or any other appropriate irregular or regular shape. The legs may be adjustable, in some implementations. For example, the legs may include an adjustable leg assembly as described in U.S. Pat. No. 8,622,355 entitled “Extendible leg assembly and retaining system.”

A leg may include a first end and a second opposing end. The first end of a leg may be disposed proximate a table top, when the table top is in the second position. A second end of the leg may be proximate the ground. In some implementations, the legs may include one or more feet proximate the second end of a leg. For example, the legs may include feet that include wheels (e.g., castors) to facilitate moving the flip-top table. In some implementations, a leg may include an arched foot, a c-shaped foot, multi-contact point foot (e.g., the foot may contact the ground at several points and/or the foot may be coupled to more than one wheel which contacts the ground) and/or wheels. For example, the foot of a leg may have an arched shape such that the leg is coupled to a center of a curvature of the arched shaped foot. The arched foot and/or c-shaped foot may include at least two portions that contact the ground and/or may include wheels that contact the ground. The arched foot and/or c-shaped foot may increase the stability of the table (e.g., when compared with a foot with a single contact point with the ground and/or wheels). Wheels may facilitate moving the table, in some implementations.

The crossbar may couple one or more legs of the table together. For example, a crossbar may include a first end and a second opposing end. The first end of the crossbar may be coupled proximate a first end of a first leg and the second end of the crossbar may be coupled proximate a first end of a second leg.

In some implementations, the crossbar may disposed proximate a middle portion of the table top (e.g., when the table top is in the second position). The crossbar may be coupled to the frame and/or the table top such that the crossbar is disposed in approximately the center of the width of the cross-section of the table top.

In some implementations, the crossbar of the frame may be coupled to the legs (e.g., two or more legs). The crossbar of the frame may be coupled to the table top proximate to the bottom surface of the table top, when the table top is in the second position. The crossbar (e.g., a top surface) may contact the bottom surface of a table top in the second position. In some implementations, a gap may exist between the bottom surface of the table top and the top surface of the crossbar. For example, the gap may be greater than approximately 1.5 in. The gap may be less than approximately 1 foot in some implementations. The gap may be selected comply with pinch hazard regulations (e.g., classroom standards, industry standards, etc.).

FIG. 1A illustrates front view of an implementation of an example flip-top table 100, in which the table top is oriented in the first position. FIG. 1B illustrates a side view of the example flip-top table 100, illustrated in FIG. 1A, in which the table top is oriented in the second position. FIG. 1C illustrates a front view of the example flip-top table, illustrated in FIG. 1B. The flip-top table 100 includes a table top 110 coupled to a frame 120.

The table top 110 includes a cross-section 112 and a depth 114. An axis x 116 (e.g., in the direction of a length of a table top) and an axis y 118 (e.g., in the direction of the width of the table top) are parallel to the cross-section 112, perpendicular to each other, and form a plane x-y. The cross-section 112 is disposed in the plane x-y. The plane x-y rotates with the rotation of the table top.

The frame 120 (e.g., legs and/or crossbar) may be coupled to the table top 110. For example, the frame 120 and the table top 110 may be coupled (e.g., via hinges) to allow rotational movement of the table top. Thus, the table top 110 may be rotated into different positions.

The frame 120 and portions there of (e.g., crossbar and/or legs) may have any appropriate shape. Different portions of the frame may include different shapes or similar shapes. The frame (e.g., crossbar and/or the legs) may include materials such as plastics, metals, rubber, composite materials, and/or any other appropriate material. The material(s) selected to be included in the frame (e.g., crossbar and/or the legs) may allow the frame of the table to be formed with a predetermined strength (e.g., to support of the weight of the table top, people, books, etc.). Different parts of the frame may be formed of similar or different materials.

A frame 120 may have a height, width, and length. An axis z 122 is parallel to the height of the frame. For example, the axis z 122 may be parallel to the length of the legs and/or perpendicular to the ground on which the table rests.

As illustrated in FIG. 1A, the table top 110 is oriented in the first position. In the first position, the table top 110 is disposed approximately parallel to the legs and/or approximately perpendicular to a top surface of the ground (e.g., the x-y plane in which the cross-section of the table top resides is approximately parallel to the z-axis and/or the x-y plane in which the cross section of the table top resides is between approximately 170 degrees and approximately 190 degrees). In some implementations, at least a portion of the table top 110 may contact leg(s) of the table. For example, a bottom portion 119 of the table top 110 may contact the frame 120. The table top 110 may be disposed in the first position to facilitate moving the table 100. In some implementations, the table 100 may be nested with one or more other tables for storage.

As illustrated in FIG. 1B, the table top 110 is oriented in the second position. In the second position, the table top 110 is disposed approximately perpendicularly to the legs and/or approximately perpendicular to a top surface of the ground (e.g., the x-y plane in which the cross-section of the table top resides is approximately perpendicular to the z-axis).

In some implementations, the table top 110 is oriented in a third position. In the third position, the table top 110 is disposed slanted relative to the legs and/or a top surface of the ground (e.g., the x-y plane, in which the cross-section of the table top resides, is slanted relative to the z-axis; and/or the x-y plane, in which the cross-section of the table top resides, is between 90 degrees and 180 degrees relative to the z-axis).

As illustrated, the frame 120 includes a crossbar 130 coupled to two legs 140. Although, the legs are illustrated in FIGS. 1A and 1B as similar, a leg in a flip-top table may be similar and/or different to other leg(s) in the flip-top table. Each leg 140 may include a first end 142 and an opposing second end 144. As illustrated, the crossbar 130 may be coupled proximate the first end 142 of the legs 140.

The crossbar 130 may be coupled to the frame 120 and/or the table top 110 such that the crossbar is disposed in approximately the center of the width 113 of the cross-section of the table top. FIG. 1D illustrates an implementation of an example table top 110. The table top includes three portions: a front portion 150, a middle portion 152, and a back portion 154. The areas (e.g., of the cross-section) included in portions 150, 152, and 154 may be approximately equal. In some implementations, the length and/or width of each portion may be approximately equal. A cross bar 130 of the frame 120 may be disposed proximate the middle portion 152 of the table top 110. For example, when the table top 110 is in the second position, the crossbar 130 may be proximate a bottom surface of the middle portion of the table top.

The legs 140 may be coupled to the frame 120 and/or table top 110 such that the legs may be disposed in approximate the center of the width of the cross-section of table top. For example, the legs 140 may be disposed proximate the middle portion of the table top (e.g., middle portion 152 illustrated in FIG. 1D), when the table top 110 is in a use position, such as the second position. By disposing the legs 140 and/or the crossbar 130 proximate the center of the table top 100, the table 100 may be more stable (e.g., than a table with legs disposed along an axis parallel to the width of the table closer to one side than another side). For example, tipping of the table 100 may be inhibited when the legs 140 and/or crossbar 130 are coupled proximate the center of the table top 110 (e.g., when the orientation of the table top is quickly changed, when people sit on the table, when moving the table, etc.). In some implementations, if a person sits on an edge of the table, the table may be inhibited from tipping over when the legs are disposed proximate the center of the width of the cross-section of the table top. In some implementations, when the table is nudged or otherwise bumped into, the table may be inhibited from tipping over when the legs are disposed proximate the center of the width of the cross-section of the table top.

A change in the orientation of the table top 110 may be inhibited by activating one or more locks 160. The locks 160 may include any appropriate locking mechanism. In some implementations, the locks may be easy to use. By providing easy to use locks, children may be able to engage and/or disengage a lock, a lock may be operated quickly, and/or a lock operation may be intuitive, in some implementations. For example, locks may include slot and key (e.g., bar key and/or hook key), recesses and levers, and/or other appropriate locks. A slot and key lock may be simple to operate. The slots in slot and key locks may include bumpers (e.g., integrated and/or separate). The bumpers may reduce noise during orientation changes (e.g., when compared with not using bumpers) and/or reduce wear and tear (e.g., by reducing the impact of forceful contacts), for example. The locks 160 may be utilized to secure (e.g., coupling and/or restricting movement) the table top 110 in a predetermined orientation (e.g., first position, second position and/or third position).

The locks 160 may be disposed on the legs 140, crossbar 130, and/or table top 110. A lock may include two or more parts. For example, a lock may include a first part and a second part, which receives the first part (e.g., to couple two objects and/or to inhibit rotation of a table top, and/or secure a position). In some implementations, a first part of a lock may be disposed on one component and a second part of a lock may be disposed on a second component. The second part of the lock may receive the first part of the lock to couple the first component and the second component. For example, the lock may include a key and a slot. The key may be disposed on a first component and the slot may be disposed on a second component. By positioning the key and slot on different components, the components may be coupled together when the table is in a predetermined position. Components may be inhibited from coupling together when the table is in one or more other positions (e.g., since the key and the slot may not be aligned for coupling).

In some implementations, at least a portion of the lock(s) 160 may be disposed in the middle portion of table top (e.g., middle portion 152 of table top 110 illustrated in FIG. 1D). For example, the first part(s) of lock(s) adapted to inhibit movement of a table top in a second position, may be disposed in the middle portion of the table top. In some implementations, the second part(s) of lock(s) adapted to inhibit movement of a table top in a first position may be disposed in a middle portion of the table top.

FIG. 1E illustrates an implementation of example table top 110. FIG. 1F illustrates an implementation of example crossbar 130. As illustrated, two types of locks are coupled to the table, a bar key and slot lock and a hook key and slot lock. The bar key and slot lock includes a bar key 161 and a first slot 162, which couples with the bar key. The bar key 161 may include a handle 163 and a bar portion 164. The bar key 161 may be coupled to the table top via a coupler 165 (e.g., fastener such as a screw and/or bolt). The coupler 165 may allow at least partial rotation of the bar key 161 in a plane parallel to the bottom surface of the table top (e.g., x-y plane). The first slots 162 may be disposed in the crossbar 130. A first slot 162 may receive the bar portion 164 of the bar key 161. For example, the slot may have a size and/or shape to allow at least a portion of the bar portion of the bar key to be disposed in the first slot. In some implementations, the table may include at least two bar key and slot locks. A first bar key and slot lock proximate a first side of the table and a second bar key and slot lock proximate a second opposing side of the table. The bar key and first slots may be disposed across a width of the table to inhibit inadvertent pinch hazards and/or to increase stability. For example, if a single lock is utilized proximate one of the legs to inhibit the rotation of the table top from the second position to the first position, a user may be able to create a gap and/or pinch hazard proximate the other leg. A user may be able to create the gap by lifting the table top proximate the other leg up and creating the gap and/or pinch hazard between the bottom surface of the table top and the other leg and/or portion of the crossbar. By disposing the bar key at least partially in the first slot, the table top may be coupled to the crossbar and/or frame in the second position and/or third position(s). A change in the orientation of the table top from the second position and/or third positions may be restricted by the bar and key lock(s). In some implementations, more than two bar key and slot locks may be utilized to inhibit rotation of the table top from the second position to other positions. In some implementations, one or more bar key and slot locks may be utilized to inhibit rotation from the first position, the third position, and/or other positions.

The hook key and slot lock may include a hook key 166 and a second slot 167. The hook key 166 may include a handle 168 and a hook portion 169 (e.g., j-shaped hook). The hook key 167 may be coupled to the crossbar 130 via a coupler 170 (e.g., fastener such as screw and/or bolt). The coupler 170 may allow at least partial rotation of the hook key 167 in a plane parallel to the bottom surface of the table top 110 (e.g., x-y plane). The second slot 167 may receive the hook portion 169 of the hook key 166. For example, the second slot 167 may have a size and/or shape to allow at least a portion of the hook portion 169 of the hook key 166 to be disposed in the second slot 167. In some implementations, the second slot 167 may include a portion adapted to engage with the hook portion 169 of the hook key 166 (e.g., a bar for the hook portion of the hook key to engage, an edge of the slot for the hook portion of the hook key to engage). By coupling the hook key 166 and the second slot 167, the table top 110 may be coupled to the crossbar 139 and/or the frame 120 in the first position. A change in the orientation of the table top 110 may be restricted by lock(s) 160, such as the hook and key lock.

In some implementations, more than one bar key and slot lock 161 may be used to inhibit rotation of a table top in a second position. In some implementations, one or more hook key and slot locks may be utilized to inhibit rotation of the table top between two orientations of the table top (e.g., from second position to the first position, from the first position to the third position, from the third position to the second position, from the second position to the third position).

The bar key and slot locks 161 may be disposed along a length of the table top. As illustrated, a first bar key may be disposed proximate a first end of a table top and a second bar key may be disposed proximate a second opposing end of the table top. The slots corresponding to the bar keys may be similarly disposed along a length of the crossbar (e.g., a first slot may be disposed proximate a first end of the crossbar and/or a second slot may be disposed proximate a second opposing end of the crossbar).

FIG. 2 illustrates an implementation of an example flip-top table 200. The flip-top table 200 may include a table top 210 and a frame 220. The frame 220 may include legs 230 coupled to a crossbar 240. The legs 230 may include a first end 250 and an opposing second end 255. The crossbar 240 may couple the legs proximate the first ends 250 of the legs 230.

In some implementations, at least one leg of the table 200 may include a retractable stop. As illustrated, each leg 230 of the table 200 may include a retractable stop 260. A top portion of the leg may include a recess and the retractable stop may be disposed at least partially in the recess. For example, at least a portion of the leg may be hollow and the retractable stop may be disposed at least partially in a lumen of the hollow leg. The retractable stop may include a first part and a second part. The an outer surface of the first part may at least partially contact at least a portion of the inner surface of the recess of the leg, in which the retractable stop is disposed. The second part of the retractable stop may be disposed at least partially in the first part. The second part may move relative to the first part of the retractable stop when a force is applied to and/or removed from the first part.

The retractable stop 260 (e.g., a top surface of a retractable stop) may be positionable in a first position and at least one second position based on the amount of force applied to a top surface of the retractable stop. For example, the retractable stop 260 may be disposed in a first position initially and when force (e.g., force greater than a first force to compress the spring) is applied to the retractable stop 260, the retractable stop may be disposed in a second position.

The retractable stop may inhibit pinching of fingers, hands, clothing, etc (e.g., between the table top and the top surface of the legs and/or the top surface of the crossbar). When the table top is moved from a first position to a second position, the table top may contact the retractable stop prior being oriented in the second position. To allow the table top to be oriented in the second position, a force may be applied to the retractable stop (e.g., by exerting a force on the table top). To maintain the compression of the spring, lock(s) 270 may be utilized. In some implementations, if the force (e.g., from the lock and/or from a user) is removed from the retractable stop (e.g., lock released, user removes force from the table top, etc.), the table top may be moved from the second position by the movement of the retractable stop. For example, the retractable stop may include a spring disposed in a housing. The spring of the retractable stop may exert a force on the housing to inhibit the retractable stop from being moved from an initial position. When a first force is exerted on the top surface of the housing (e.g., from a second force that is applied to a table top), a force may be applied to the spring and be compressed. When the force is removed from the housing of the retractable stop, the spring may expand and return the retractable stop to its initial position.

FIG. 3A illustrates an implementation of an example portion 300 of a table that includes retractable stop, in a first position. FIG. 3B illustrates an implementation of the example portion 300 of the table that includes the retractable stop, in a second position. As illustrated, the retractable stop 310 may be disposed in a recess 320 of a leg 330. An outer surface of the first part of the retractable stop may contact at least a portion of an inner surface of the recess 320 of the leg 330. The retractable stop 310 may include a first opening 323 adapted to receive at least a portion of the first fastener 344 (e.g., pin, screw, brad, and/or any other appropriate fastener). The first pin 344 may couple the retractable stop 310 and the leg 330 of the frame. In some implementations, the first part of the retractable stop may include the first opening 323 and the second part may include a second opening 324. The second opening may be adapted to receive at least a portion of the first fastener 344 and allow movement of the second part relative to the first part. The second opening may be a slot that allows movement of the second part of the retractable stop relative to the first part. For example, the first fastener may be proximate a first end of the slot when the retractable stop is in the first position and the first fastener may be proximate a second opposing end of the slot when the retractable stop is in the second position.

The retractable stop 310 may include a housing 312 and a spring 314. The spring 314 of the retractable stop may exert a force against the top portion 313 of the housing 312. For example, the spring 314 (e.g., when it is fully expanded) may exert a force against the housing that allows the second part of the retractable stop to be disposed in the first position. The first part of the retractable stop (e.g., the part that contacts the leg) may not be substantially moved when the first part moves. The spring 314 may be disposed in the housing 312 to inhibit movement of the retractable stop 310 from the first position to the second position. As illustrated in FIG. 3A, the spring may not be compressed and/or not fully compressed in the first position. As illustrated in FIG. 3B, the retractable stop 310 may be compressed to dispose the retractable stop in the second position. For example, when the spring is at least partially compressed, the second part of the retractable stop may be disposed in the second position and/or the first part may not be substantially moved. In the second position, the housing 312 of the retractable stop may be at least partially in contact with a top portion of the leg 330. For example, a bottom surface of the top portion 313 of the housing 312 of the retractable stop 310 may contact at least a portion of the top surface of a leg 330.

The spring 314 may be compressed in the second position. When the retractable stop 310 is in the second position, the spring 314 may exert a greater force against the top portion 313 of the housing 312 than when the retractable stop is in the first position. Thus, when the force applied to the spring to dispose the retractable stop in the second position is removed (e.g., a person lets go of the table top), the spring may return to a less compressed position and the retractable stop may return to the first position.

In some implementations, the retractable stop 310 may include guides along which the second part of the retractable stop may move relative to the first part. For example, the housing 312 may include recess(es) and protrusion(s) that are disposable in recess(es). As illustrated, the retractable stop 310 may include a pair of protrusion 321 disposed on the first part of the retractable stop and a pair of recesses disposed on the second part of the retractable stop. As the second part of the retractable stop moves relative to the first part, a protrusion may travel in a recesses disposed in the second part. The retractable stop may include a guide on opposing sides of the retractable stop to maintain an alignment of the first part relative to the second part (e.g., to inhibit the first part from getting misaligned and stuck, to keep movement smooth, etc.).

In some implementations, a top portion of the housing of the retractable stop may still be slanted. As illustrated, the top portion 313 of the housing 312 may be slanted (e.g., at an angle greater than 90 degrees and less than 180 degrees relative to the sides of the housing). The top portion 313 may be slanted such that when the top table top moves between the first position of the table top to the second position of the table top, a bottom surface of the table top contacts a top slanted surface of the housing of the retractable stop. The slanted surface may inhibit pinching fingers, hands, and/or clothes between the table top and the frame. By inhibiting pinching when changing a table top orientation, the table may be more easily used in classrooms and other appropriate facilities.

In the second position, the housing of the retractable stop may be disposed approximately parallel to and/or below a top surface of a leg of the table.

The retractable stop may include housings of any appropriate size and/or shape. The retractable stop may also remain slanted in the second position and/or not remain slanted in the second position. The retractable stop may operate in a variety of methods to allow the movement of the retractable stop from the first position to the second position.

FIG. 3C illustrates an implementation of an example portion 350 of a table in which a retractable stop is disposed in a first position. FIG. 3D illustrates an implementation of the example portion 350 of a table, illustrated in FIG. 3C, in which a retractable stop is in the second position.

An outer surface of the first part of the retractable stop may contact at least a portion of an inner surface of the recess 320 of the leg 330. The retractable stop 310 may include a first opening 323 adapted to receive at least a portion of the first fastener 344 (e.g., pin, screw, brad, and/or any other appropriate fastener). The first pin 344 may couple the retractable stop 310 and the leg 330 of the frame. In some implementations, the first part of the retractable stop may include the first opening 323 and the second part may include a second opening 324. The second opening may be adapted to receive at least a portion of the first fastener 344 and allow movement of the second part relative to the first part. The second opening may be a slot that allows movement of the second part of the retractable stop relative to the first part.

The first part and the second part of the retractable stop may be coupled via a hinge 352. The hinge may allow movement of the second part of the retractable stop relative to the first part of the retractable stop. The hinge may include a third opening 326 adapted to receive a second fastener 342. The hinge may allow the second part to at least partially rotate upwards and downwards relative to the second fastener 342. In some implementations, the housing may be coupled to the leg of the frame via the second fastener of the hinge and/or may not be coupled to the leg via the first fastener.

As illustrated, the top portion of the retractable stop 350 may be slanted in the first position and in the second position the top portion is less slanted than when in the first position. For example, the top portion of the retractable stop may be allowed to pivot downwards as a force is applied to the retractable stop (e.g., by a table top).

FIG. 3E illustrates an implementation of an example portion of a table in which a retractable stop 375 is disposed in a first position. FIG. 3F illustrates an implementation of the example portion 375 of a table, as illustrated in FIG. 3E, in which the retractable stop 375 is disposed in a second position.

The retractable stop 310 may include a first opening 323 adapted to receive at least a portion of the first fastener 344 (e.g., pin, screw, brad, and/or any other appropriate fastener). The first pin 344 may couple the retractable stop 310 and the leg 330 of the frame. In some implementations, the first part of the retractable stop may include the first opening 323 and the second part may include a second opening 324. The second opening may be adapted to receive at least a portion of the first fastener 344 and allow movement of the second part relative to the first part. The second opening may be a slot that allows movement of the second part of the retractable stop relative to the first part.

As illustrated in FIGS. 3E-3F, the top portion of the housing may remain slanted as it moves from the first position to the second position. As illustrated, at least a portion of the top portion may be disposed below a top surface of the leg, in some implementations.

To maintain the compression of the spring, and thus maintain the table top in the second position, lock(s) may be utilized. Any appropriate lock may be utilized. As illustrated in FIG. 2, a lock 270 may be disposed proximate a center of a crossbar 240. In some implementations, the lock 270 may include more than at least two parts. For example, a lock may include a first part and a second part, which receives the first part (e.g., to couple two objects and/or to inhibit rotation of a table top, and/or secure a position). The first part of the lock may be coupled to the table top 210 and the second part may be coupled to the crossbar 240. When the tabletop is in a use position (e.g., second position or at least one of the third positions), the first part of the lock may engage the second part of the lock to inhibit rotation of the table top.

For example, when rotating a table top from a first position to a use position (e.g., a second position), a user may grip the table top. The user may then exert a force to the table top to rotate the table top to the use position. Before the table top resides in the second position, the bottom surface of the table top may contact the retractable stop(s) of the table. Thus, if a user lets go of the table top (e.g., slams the table top, looses control of the table top, etc.), by contacting the retractable stop prior to being oriented in the second position, pinching hazards may be inhibited. To orient the table top in the second position, the user may then apply a force on the table top and engage the lock to inhibit rotation of the table top. To return the table top to an upright position (e.g., first position), the user may release the lock. Since the lock maintains a force on the retractable stop, by releasing the lock, the force on the retractable stop is reduced and the table top may move from the second position (e.g., the force of the spring expanding may exert an upwards force on the top surface of the retractable stop and thus the table top). A user may then grip the table top and rotate (e.g., flip) the table top to an upright position. In some implementations, the user may lock the table top using lock(s) to inhibit rotation of the table top from the upright position.

In some implementations, more than one lock may be utilized. A table may include first lock(s) to inhibit the rotation of a table top in a first orientation (e.g., secure the table top in the first position) and second lock(s) to inhibit the rotation of the table top in one or more other positions, such as the second or third positions (e.g., secure the table top in the second position, secure the table top in one of the third position(s), etc.). For example, one or more of the locks as illustrated in FIGS. 1A-1C may be utilized to inhibit movement of the table top from a predetermined position.

In various implementations, a flip-top table may include a table top, and a frame. The table top may be adjustable between a first position and a second position. The frame may be coupled to the table top. The frame may include at least two legs and a crossbar coupling at least two of the legs together. The frame may include two or more first locks and at least one second lock. A first lock may include a first key coupled to a bottom surface of the table top, and a first slot disposed in the crossbar. The first slot may receive at least a portion of the first key. The first lock may inhibit rotation of the table top from the second position when the first key is engaged with the first slot. The second may include a second key coupled to the crossbar and a second slot disposed in the table top. The second slot may receive at least a portion of the second key. The second lock may inhibit rotation of the table top from the first position when the second key is engaged with the second slot. The flip-top table may include at least one retractable stop disposed at least partially in an end of at least one of the legs. A retractable stop may include a housing and a spring at least partially disposed in the housing. The housing may include a slanted top portion. The retractable stop may include a first position when a first force is not applied to the top surface of the retractable stop, and a second position when the first force is applied to the top surface of the retractable stop. A first force compresses the spring. In some implementations, when the table top is moved from a first position to a second position, a bottom surface of the table top contacts at least one of the retractable stops prior to the table top being oriented in the second position, and a force greater than the first force is applied to the retractable stop to allow the table top to be oriented in the second position.

Implementations may include one or more of the following features. The first lock(s) may include bar key and slot lock(s). A bar key and slot lock may include a bar key and a first slot. In some implementations, the flip-top table may include two or more first couplers and a second coupler. The first bar key(s) may be coupled to the bottom surface of the table top via a first coupler. A first coupler may allow a bar key to be at least partially rotated. The second hook key may be coupled to the bottom surface of the table top via the second coupler. The second coupler may allow the hook key to be at least partially rotated. The flip-top table may include one or more additional second couplers, which may inhibit movement of the table top when the table top is oriented in the first position. A first coupler may inhibit rotation of the table top when the table top is in a third position. A top surface of the table top in the third position may be slanted. A retractable stop may return to the first position when the first force is removed from the retractable stop.

In some implementations, a legs may include an arched foot and/or one or more wheels. One or more wheels may be coupled to at least one end of the arched foot of a leg, in some implementations. A leg may be extendable (e.g., a height of a table may be adjusted by extending and/or unextending a leg).

In various implementations, a flip-top table may include a table top adjustable between a first position and a second position and a frame coupled to the table top. The frame may include at least two legs and a crossbar coupling the two legs together. The frame may include at least one second lock. At least one of the second locks may include a second key coupled to the crossbar and a second slot disposed in the table top. The second slot may receive at least a portion of the second key.

A retractable stop may include a housing and a spring disposed at least partially in the housing. The housing may include a slanted top portion. The retractable stop may include a first position when a first force is not applied to the top surface of the retractable stop. The retractable stop may include a second position when the first force is applied to the top surface of the retractable stop, and a first force may compress the spring. When the table top may be moved from a first position to a second position, a bottom surface of the table top may contact at least one of the retractable stops prior to the table top being oriented in the second position. A force greater than the first force may be applied to the retractable stop to allow the table top to be oriented in the second position.

Implementations may include one or more of the following features. Applying the first force to at least one of the retractable stop may include applying a second force to the table top to compress the spring of the housing of the retractable spring.
